No, 64 bit was widely adopted long before windows cut support. Keep in mind a 32 bit OS can only use ~4GB of ram, and most systems have been shipping with more than that for many years now.
Wasn’t 64 but adoption largely driven by Microsoft deciding they weren’t making a 32 but version of their next Windows at one point? It seems it might take something similar.

Towards the end of 32 bit’s life, physical address extension allowed operating systems to use more memory, often up to 40 bits worth, but still could still expose a 32 bit address space to user applications.

Yes, but that would only get the total up to about 5GB, which isn’t very much more.

2^40 is a terabyte

Microsoft supports 32 bit processors still with windows 10. They died out because it was becoming clear that 4GB of memory wasn’t going to be enough for applications, and the low margins on budget chips didn’t warrant maintaining 32 bit designs when the 64 bit versions would do and could still run the 32 bit software.
